UNITED S'IA'lfliS PATENT Specification of Letters Patent.

Patented April 3, 1906.

Application filed November 28,1905. Serial No. 288,761.

To all whom, it may concern.-

Be it known that I, ARTHUR WALTER LEWIS, a citizen of the United States,residing at Moscow, in the county of Hickman and State of Kentucky, haveinvented certain new and useful Improvements in Car-Couplers andDraw-Heads; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference eing had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in carcouplers anddrawheads; and it consists in the provision 0; means whereby thedraw-heads may be supported by interlocking wings as the couplers arereleased, and comprises various details of construction and combinationsand arrangements of parts, which will be hereinafter fully described,and then specifically defined in the appended claim.

My invention is illustrated in the accompanying drawings, in which--Figure 1 is a top plan view of my invention, showing the two couplersconnected together. Fig. 2 is a side elevation, and Fig. 3 is an endview of one of the coupler-heads and laterally-extending inclined wings.

Reference now being had to the details of the drawings by letter, A Adesignate two coupler-heads, each having a forked end and each beinrecessed. C C designate two angled coup ers, each pivotally mounted upona pin D, held in one of the arms at the forked end of each coupler-head.E designates a gravity coupling-pin mounted in apertures in thecoupler-heads and designed to hold an arm of each angled coupler withinthe chambered or recessed portion of the head, as shown in Fig. 1 of thedrawings.

Projecting from the opposite edges of each coupler-head are the wings Fand F, which project spirally in alinement with each other from oppositesides of the coupler-heads, one of said wings being upwardly inclined,While the other is downwardly inclined, and each wing is provided with.a contracted portion midway its length. The upper face of the wing F isbeveled to a thin edge F and the under surface of the wing F issimilarly beveled, as at H. (Shown clearly in Fig. 3 of the drawings.)Each coupler-head is provided with similar wings which when they cometogether the inclined surface H of one wing will contact with theinclined surface of the upper face of the wing F, thus guiding the twodraw-heads so that the couplers will interlock in the manner shown inFig. 1 of the drawings.

From the foregoing it will be observed that by the provision of acoupler apparatus as shown and described means is afforded for holdingthe draw-heads from dropping upon the tracks of a railway in case of anybreakage and while a train equipped with the couplers is in motion.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

A car-coupler comprising two heads, each having a recessed end, and achambered portion in the edge thereof, an angled coupling pivotallymounted within each chambered portion, Wings projecting from theopposite edges of each coupler-head and in alinement with each other andspirally arranged, each of said wings having a contracted shank portionmidway of its length and the free end of each wing widened and beveledin opposite directions, as set forth.

In testimony whereof I hereunto aiflix my signature in the presence oftwo witnesses. ARTHUR WVALTER LEWIS.
